Hi guys

Need help deciding what turbos im gonna use next

Currently running gtss turbos on e85 and making 368 kw at the rears.

I want more power but no more lag

What are my options?

Iv heard borg warner turbos are good

Any suggestions?

Keep in mind I dont want it to be laggy and its a street car

Thanks!

In terms of twin options I think your about out of luck, the amount of power u are making with those turbos is quite decent.

Next step would be to either go stroker kit with -5s so u don't lose the response or go to a single set up

In saying that you haven't really described ur set up

Agreed.

More boost will still give you more torque, but it will heat the charge air also.

Opening up any restrictions will help a little, as may cams etc. HKS Vcam if you can find one perhaps?

How much more power are you chasing ? What can the current internals handle , as scotty quoted charge air temp with more boost (water injection setup ? extra injector plumbed into plenum) ,... what rpm range suits your driving , how many demerit points can your licence handle....lol... pac performance got 1000hp ,maybe give them a call for setup options that they tried . 368kw is a fair wack of power at the treads and can be hard to put it down efficiently with out smoke...unless thats what your chasing...... bigger single turbo= more lag time with incorrect cam timing ... poor cam timing will create rough idle and poor slow speed drive ability ...hope that makes sense ive had a beer or two :cheers:

    • But if I smoke test 5th cylinder it’s all ok, no leaks  when I try with 2nd it’s leaking exhaust and intake, it doesn’t come from oil dip stick.    so maybe when car was running poorly, rich or sth. Spark plugs were black and covered in charcoal or sth lookalike. could potential contamination make valves not seal properly? is there also a possibility that rb’s don’t have equal performing cooling passages  meaning back of the engine will be hotter than front. Can this cause improper wear if engine was running under load for short time? Or carbon build up could just burnt from 4-6 and is still on 1-3?   I out of my head like really. Timing is as manual crank-exhaust 47, exhaust-intake 38 at this point I thinking about give it a try and make another 500-1000km and check if anything change, if not I will most likely disassemble engine head /or whole engine and send it back to rebuild. It’s killing me     
    • Thanks Duncan, I don't have a GTR these days mate. Gone soft..
    • Yeah. air pressure leakdown test is where I would be headed next here, using one's ears to determine whether it's the valves or bores/rings leaking...
    • More likely you didn't bed the rings in correctly and have glazed the bores. Running with misfires on a fresh build is somewhat of a no-no. Surely no-one "smoke tests" the combustion chamber? That's what a leakdown test is for. Smoke testing is, um, a bit of a wank at best, and only really useful for external pipework.  
    • Well, obviously that kit is not a relocation kit or anything other than just the original isolators and the like. I would suggest that it should be a matter of just bending up some flat bar to build a mount over the top of some other diff, with the flat bar held to the back of the diff by the rear hat bolts. A little welding, a little thinking about how to secure the front of this structure, maybe some different hoses in case you can't get it in just the right place.
